中草药添加剂对荷斯坦奶牛产奶量及抗热应激能力的影响(英文) 总被引：12，自引：0，他引：12
[Objective] The research aimed to explore the effects of Chinese herb additive on milk yield and anti-heat stress ability of Holstein cow.[Method] 36 Holstein cows with similar birth order and milk yield were equally and randomly divided into 3 groups which were control group, Chinese medicine Ⅰ group and Chinese medicine Ⅱ group. In control group, cows were fed with basic feed, while in Chinese medicine Ⅰ group, cows were fed with basic feed containing 4% compound Chinese herb additive and in Chinese medicine Ⅱ group, cows were fed with basic feed containing 3% compound Chinese herb additive.All cows in the 3 groups were analyzed comparatively.[Result] Adding some compound Chinese herb additive into basic feed would increase milk yield and anti-heat stress ability of Holstein cow,besides,it also could decrease cow diseases such as cow mastitis.Chinese medicine Ⅰ would generate the highest economic benefit of practical production.[Conclusion] Adding Chinese herb additive into basic feed is an effective way for reliefing heat stress and increasing milk yield. 相似文献

中草药添加剂对荷斯坦奶牛产奶量及抗热应激能力的影响 总被引：7，自引：0，他引：7
[目的]探讨中草药添加剂对泌乳牛生产性能及抗热应激能力的影响。[方法]选取胎次和产奶量基本相同、健康的荷斯坦奶牛36头,随机分为3组,对照组饲喂基础日粮,中药Ⅰ组饲喂含4%复合中草药添加剂的基础日粮,中药Ⅱ组饲喂含3%复合中草药添加剂的基础日粮,进行对比分析试验。[结果]在泌乳奶牛基础日粮中添加一定量的复合中草药添加剂可提高泌乳奶牛产奶量及抗热应激能力,并能有效减少奶牛乳房炎等疾病的发病率,提高生产的经济效益,以中药Ⅰ组效果更好。[结论]在奶牛基础日粮中添加中草药添加剂是缓解热应激、提高奶牛夏季产奶量的有效途径之一。 相似文献

高温胁迫─小麦超高产的主要障碍 总被引：10，自引：1，他引：10
小麦是冷季作物，最适生长温度为１５～２０℃。我国由于受季风的影响，夏季是同纬度除少数沙漠干旱地区以外最热的国家，淮河一秦岭以北冬小麦集中产区，小麦抽穗～成熟的日平均气温大于３０℃的高温天气占到该生育期的１／３，大约７０％的时间突破了临界温度。北方受高温干热风影响的小麦面积占到小麦播种面积的７１％，为害频率为十年七遇，小麦年减产１８．５～３５亿ｋｇ，热胁迫危害成为我国北方小麦高产的主要生理障碍。小麦耐热基因型与热敏感基因型存在广泛的变异，耐热品种的干物质积累显著高于热敏感品种，为小麦抗热筛选提供了依据。提高小麦的抗热性水平，缓解胁迫为害，是今后小麦超高产育种的重要方向。 相似文献

米曲霉提取物对瘤胃生态及奶牛生产性能的影响 总被引：1，自引：0，他引：1
米曲霉（Aspergillus Oryzae）是FAO／WHO公认安全的食品级菌种，其发酵提取物艾美福（Amaferm）通过刺激纤维素分解菌的生长，提高纤维素酶的产量，提高饲草中纤维的消化率，改善反刍动物瘤胃生理功能，稳定瘤胃pH值，从而达到降低奶牛代谢疾病，提高反刍动物的生产性能及体况，显著提高奶牛抗热应激的能力。 相似文献
